hello,
I want opensesame to keep repeating a trial till the person makes a response. the trail would contain a hidden word masked by other word. The hidden word is to be identified by the participant and press a key as soon as they identify it. They will be asked to type the word after this. The reaction time from stimulus presentation till the word is typed in will be measured.
can you please help me figure out how to do this?

I'd need help in creating a 2-Back Task with digits in which I have 2 blocks containing a tot number of MATCH trials and MISMATCH trials. In the first block, the MISMATCH condition has no lures, whereas the second block contains some lures. Is there anyone who could help me dealing with this? Thank you.
